Unknown
This airplane began life as a Lancair kit, got certified as the Columbia 400, and ended up wearing a Cessna badge as the TTx. All-composite, turbocharged, and startlingly fast for something with fixed gear — it traded wheels-up complexity for slick aerodynamics and won.
Fun fact
It cruises at 235 knots with the landing gear welded down — among the fastest fixed-gear certified singles ever built.
How to spot one
Sleek composite low-wing that looks like a Cirrus at first glance — the tell is the fixed gear with wheel pants and no parachute hatch outline on the fuselage.
